a Graph the function y x3 21x2 143x 315 using the window

(a) Graph the function y = x^3 + 21x^2 + 143x + 315 using the window [- 10, 10] by [-10, 10]. (b) Is the graph complete? (a) Choose the correct graph below. [-10, 10] by [-10, 10], X_scl = 1 Y_scl = 1 (b) Is the graph of the function y = x^3 + 21x^2 + 143x + 315, shown in the previous step, complete? Yes No

Solution

Here the degree is 3 which is odd and leading coefficient is positive .

So it starts downwards and end upwards.

Correct option is D.
